Abstract: An optical device includes an array of lenses and a plurality of segments disposed under the array of lenses. The plurality of segments corresponds to a plurality of images. Upon tilting the device at different viewing angle, the array of lenses presents images sequentially. In some examples, individual ones of the segments can comprise specular reflecting, transparent, diffusely reflecting, and/or diffusely transmissive features. In some examples, individual ones of the segments can comprise transparent and non-transparent regions. The images can produce one or more optical effects.

Abstract: An optical product includes an array of lenses and first and second plurality of portions disposed under the array of lenses. Individual ones of the first plurality of portions can correspond to a point on a surface of a first 3D object, and include first non-holographic features configured to produce at least part of a first 3D image of the first 3D object. Individual ones of the second plurality of portions can correspond to a point on a surface of a second 3D object, and include second non-holographic features configured to produce at least part of a second 3D image of the second 3D object. The optical product can include an interference optical structure disposed with respect to the first and/or second non-holographic features.

Abstract: In certain embodiments, a master for fabricating an optical product is disclosed. For example, the optical product can be configured to be an anti-counterfeit feature such as a patch, a window, or a thread on a banknote. The optical product can be configured, when illuminated, to reproduce by reflected or refracted light, a 3D image of at least a part of a 3D object. The master can include a first surface and a second surface opposite the first surface. The second surface can include a plurality of portions. Each portion can correspond to a point on a surface of the 3D object. Each portion can include features corresponding to non-holographic elements on the optical product. A gradient in the features can correlate to an inclination of the surface of the 3D object at the corresponding point. An orientation of the features can correlate to an orientation of the surface of the 3D object at the corresponding point.

Abstract: A security device includes an array of lenses and a plurality of first and second segments disposed under the array of lenses. At a first viewing angle, the array of lenses presents a first image for viewing without presenting the second image for viewing, and at a second viewing angle different from the first viewing angle, the array of lenses presents for viewing the second image without presenting the first image for viewing. At least one first or second segment can include one or more microstructures or one or more nanostructures configured to produce one or more colors for the first or second image.

Abstract: An optical product can reproduce a first 3D image of at least part of a first 3D object and a second 3D image of at least part of a second 3D object. The optical product comprises a surface configured, when illuminated, to reproduce by reflected or transmitted light, the first 3D image without reproducing the second 3D image at a first angle of view, and the second 3D image without reproducing the first 3D image at a second angle of view. Each portion of first portions can correspond to a point on a surface of the first 3D object, and comprise first non-holographic features configured to produce at least part of the first 3D image. Each portion of second portions can correspond to a point on a surface of the second 3D object, and comprise second non-holographic features configured to produce at least part of the second 3D image.

Abstract: Implementations disclosed herein include optical sheets comprising one or more regions including one or more optical elements. Each of the one or more optical elements includes a plurality of microstructures. The one or more optical elements can be configured to tailor the radiation pattern output from a source of illumination. The one or more optical element can be further configured to impart a visual appearance to the optical sheet that is different from a standard lenticular or prismatic sheet. In various implementations, the one or more regions can be demarcated from each other or the surrounding by borders. The borders of the one or more regions can be configured to form one or more letters, one or more symbols or logos for identification and/or security purposes. Various implementations of the optical sheet can include nano-particles in addition to the optical elements to enhance the aesthetic quality of the optical film.
